What is the application of YG20 tungsten carbide block

YG20 tungsten carbide is a cemented carbide material similar to YG8, but with a higher cobalt content (~10–12% Co) and slightly lower tungsten carbide (~88–90% WC). This gives it higher toughness but slightly lower hardness than YG8, making it more resistant to chipping while still being wear-resistant.

Here’s a detailed look at its applications:

1. Cutting Tools

Ideal for medium- to heavy-duty cutting tools, such as:
- Milling cutters
- Drills
- Reamers
- Taps

Especially suitable where impact resistance is important, e.g., intermittent cutting.

2. Wear-Resistant Parts

Used in manufacturing parts exposed to abrasion, such as:
- Punches and dies
- Blanking and stamping tools
- Wear plates and liners
- Guide rails for machine tools

3. High-Impact Components

Because of higher cobalt content, YG20 is preferred for components that experience shock or impact, like:
- Mining tools
- Rock drilling bits
- Hammer tips
